Green Bay Packers WR Jordy Nelson (knee) said his surgically repaired knee is fine, but he understands why the team is limiting his work during organized team activities. Nelson has been allowed to run, lift and perform all of the drills the trainers ask him to do. Nelson has been running routes on a side field during practices. He said he will need to regain his chemistry with QB Aaron Rodgers once he is cleared to practice again.
